1. Remove the four round-head machine screws and
washers holding the stop bracket to the valve hex at each end.
Do not remove the stop bracket
2. Position the adapter plate over the stop bracket so that
the adapter plate holes match the stop bracket holes.
3. Insert the flat head screws supplied with the linkage
assembly through plate, spacers, and stop bracket and into
each hex. Tighten securely. The spacers prevent contact of
adapter plate and stop bracket. See Fig. 9.
4. Mount the lever arm (13-3/4 in. [349.3 mm]) supplied
with the motor so the load takeoff holes will be at the same
end of the valve as the valve actuating arm.
NOTE: Both motor lever and valve arm could be installed
180 degrees from the positions shown in Figs. 7 and 8, if
more convenient. Use bushing hole at the clevis.
